It's interesting that in a "blog about making culture" that he doesn't address the issue of archival. While a CMS can produce a nice snapshot for archive.org or another mirror to capture, streams are trickier, especially if they rely on the app that produced the stream(s) to work.

Wouldn't streams actually make it easier? The site that wanted to do the archiving could subscribe to the stream and slurp up the content as it became available. As far as crawling older content presumably having a stream doesn't preclude you from also having permalinks to each entry.
